仅仅是特定条件下的承诺到期收益率,非预期收益率的精 确指标 到期收益率的隐含假设
没有违约风险 投资者持有到期 每一期现金流都按照y进行再投资(忽略再投资风险)
对复杂债券预期收益率的衡量精度尤其低

YTC=6.64% YTM=6.82%

注意:
YTC、YTP、CFY与YTM同为内在收益率 存在同样局限 CFY有提前偿付率的假定
HPR = 10.85% (semiannual)
When the yield to maturity is unchanged over the period, the rate of return on the bond will equal that yield.
An increase in the bond’s yield acts to reduce its price, which means that the holding period return will be less than the initial yield.
This reduces much of the attraction of the realized yield measure.
3.8 持有期回报率Holding-Period Return
HPR = [ I + ( Pn- P0 )] / P0 where I = interest payment P1 = price in n periods P0 = purchase price
